Built a my first PC yesterday. Connected everything, turned it on all fans and LEDs working fine but no response from monitor. Please Help.
Yes I have tried each RAM separately in all slots. (2 x 2gb Corsair)
No I dont have a motherboard speaker - I probably should get one.
CPU installed correctly with thermal paste and heat sink properly clicked in (AMD Phenom II quad core black)
Yes i connected the 8 pin CPU power cable.
I have also plugged in the power for my GPU (radeon HD 6850)
Have tried a different monitor with a HDMI cable.
There are no extra standoffs touching the motherboard and I didnt drop any screws on it.
The only thing I can think of is a faulty motherboard. (I might have forced the 24pin power cable in too hard and damaged something?)
PS. I am not a computer expert Im only 16 and this is my first build.
Unfortunately there is no built-in video in my mobo but Ill try and borrow a friend's graphics card to compare. The monitor I'm using has been working with my old PC for a good few years and I would think it a huge coincidence if it decided to die just as i try out my new PC plus i tried connecting my PC to my Tv screen via HDMI and it was no use.
So I think iv cancelled it down to either a faulty video card or faulty mobo. There are a lot of posts on the internet regarding this problem but very few of them have been solved.
Thanks for your help. ill get back to you if I cant find the problem or manage to fix it.
few things to check...the ram is it on the mb qal list. with the intel memory controller built into cpu now if the ram not on the mb guild it cause a no post issue. check the stand off and i/o shield for shorting to the case. most first time builders i tell them to bread board the mb/cpu/gpu and ps on a box outside the case.if it posts there then it shorting out. check also the mb to case header that all the wires are on right. if they are also check that cmos clear jumper in the right spot. one thing to check online is the mb bios and the cpu your using. some amd cpu and mb need a bios update before they will post.
I had these exact symptoms before and in my case it happened to be a bad power supply. I'm not saying this is your problem but its not something to rule out. If possible I would try your psu in another computer.
